Lactation in the dog: milk composition and intake by puppies.

Oftedal OT.


The composition and intake of milk by mother-reared puppies was studied to compare protein and energy intakes of puppies with estimated requirements. Milk samples were obtained from five beagle bitches over the period of 7-37 days postpartum. Dog milk contained on average 22.7% dry matter, 9.47% fat, 7.53% protein, 3.81% sugar and 146 kcal gross energy per 100 g. Protein comprised 31% of milk energy. Nonprotein nitrogen averaged 0.054%, equivalent to 4.4% of total nitrogen. Milk intakes of puppies in the five litters were estimated from water kinetics following administration of deuterium oxide (D2O). D2O dilution indicated that body water comprised 72-73% of puppy body weight, and fractional turnover rate of body water averaged 0.15-0.17% per day in weeks 3 and 4 postpartum. Milk intakes were calculated as 160 +/- 5.4 g (mean +/- SEM) at 19 days and 175 +/- 5.3 g at 26 days, equivalent to 17.0 and 14.6% of body weight, respectively. Daily milk yields of the bitches averaged 964 g at 19 days and 1054 g at 26 days. Dry matter intakes of the puppies were equivalent to 3.9 and 3.3% of body weight at 19 and 26 days, respectively. Gross energy intakes averaged 223-224 kcal/ kg0 .75 per day, and protein intakes averaged 0.33-0.36 g per gram body weight gain at these ages. Estimates of the energy requirements of young puppies by the National Research Council appear to be too high.

We report the case of a 46-year-old veterinarian who developed rhinoconjunctivitis and contact urticaria (CU) on his hands and forearms after contact with dog's milk. Prick tests results revealed a positive reactions to Parietaria pollens, Dermatophagoides farinae and D.pteronyssinus, dander of cat, grass, olive (+++), and to undiluted dog's milk (++++). Control prick tests with dog's milk performed in 5 healthy veterinarians were negative. We consider it important to take into account the possibility that dog's milk may be the aetiological agent of CU in veterinarians.
